Acalibration curve was created to determine the quantity of protein in a solution. the calibration curve has the form of a straight line with the equation =0.0182x+0.007 where is the corrected absorbance of the solution and x is quantity of protein in the solution in units of micrograms (μg). determine the quantity of protein in a solution that has an absorbance of 0.276 . a blank solution has an absorbance of 0.061 .

The solution has 11.4 μg protein

Explanation:

Hi there!

The corrected absorbance will be the measured absorbance minus the absorbance of the blank that is a solution without protein.

Then, the corrected absorbance will be:

0.276 - 0.061 = 0.215

Now, using the equation of the calibration curve, we can obtain the quantity of protein present in the solution:

0.215 = 0.0182x + 0.007

(0.215 - 0.007) / 0.0182 = x

x = 11.4 μg

The solution has 11.4 μg protein

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
